I have been using AIRNAV for a couple of months,being a new user, if remote access was possible via wireless or internet connection.
Other Systems have an Ethernet option,but without spending lots of money a simple solution was needed.
I found some software on the Internet Called LOGMEIN and installed the FREE version on the AIRNAV pc.
I am able to remotely connect to this PC and run the AIRNAV software providing I have an internet connection,Password protection is included when you set up an account.
Being a service Engineer, this allows me to use my airnav system when i am working away from home or when sitting in the garden over my wireless network.
Hope this information is useful.
